Crystal Quest

In Crystal Quest, you play a renegade outer-space prospector gathering precious crystals scattered across distant galaxies. The crystals attract hostile creatures known as nasties, so collecting them means blasting through intergalactic vermin along the way.

This action shooter was developed by Nova Logic and published by Data East. It was released on September 1, 1991, for Game Boy, Nintendo Game Boy, and Sinclair ZX Spectrum.
